Abstract
Electron capture in + collisions is studied at energies of 1.0, 2.0, and 3.0 keV in the reduced angular range keV deg. Time-of-flight techniques are used for state identification, and the probability of electron capture to in an exchange collision is determined. This is shown to be the dominant exchange channel at small scattering angles. The "summed" exchange channels have a reduced cross section that is found to peak in the forward direction and shows no structure, while the cross section for capture to final ground-state channels shows some small structure at 3.0 keV for keV deg. The reduced cross section, at 1.0 keV, for capture to excited states of H (with the in its ground state) is found to have a maximum at keV deg. The results are in agreement with a previously proposed model for ion-molecule charge exchange.
